By signaling to oncoming traffic and vehicles approaching from the side, a front brake light provides an essential visual cue that a car is slowing down or preparing to stop. When the light is extinguished, it indicates that a stationary vehicle might initiate movement. According to Tomasch, this visual feedback can significantly truncate the reaction time for other road users, leading to shorter stopping distances and consequently diminishing the likelihood of accidents.

Sounds reasonable. Personally I just want front turn signals to be visible from the opposite side again.

And also like, used at all.

Here's an idea. How about we zap the drivers after they make a turn if they didn't use a turn signal beforehand? 😀

[–] njordomir@lemmy.world 15 points 2 days ago

Can we do this in the same bill as the popup spikes that take out your tires if you stop across the crosswalk? The guided RPGs replacing red light cams can wait a little longer.

Not sure if I read that correctly, but I don't think this has ever been the case?

[–] catloaf@lemm.ee 22 points 2 days ago

I mean when a car is coming at me from a cross street, I want to be able to tell if they're turning or just an asshole not using their signal. On some cars, the turn signal is mounted so far to the side that if they're approaching from my right and turning right onto the same street as me, I can't see that turn signal. Sometimes combined with the roundness of the nose exacerbating the problem.

Theres a saying in computer stuff that applies nicely here. PEBKAC, problem exists between keyboard and computer...turn signals have to be turned on, no amount of engineering can fix bad driving.

Maybe redo the driving test like... At least every 20 years? There are people on the roads who got their licenses when their town didn't even had traffic lights. People who never saw a roundabout in their first 20 years of driving.

Its nice that we restrict young people by making them take more and more driving lessons and paying more for tiered licences, like we do in Europe for motorcycles and trucks.

But maybe also take a look at the 70+ year old grandpa who had two strokes and one heart attack, has two pairs of of glasses but his license says that he's perfectly fit.

Sometimes you see those videos from a dash cam of a truck that hits a bridge, obviously the truck driver was been being inattentive but often so was the recording cars driver. All I can ever think is, "why were you so close behind, it was blindingly obvious that was about to happen", yet to them apparently it wasn't, and now they've got bits of truck roof in their windscreen.

There was an astounding number of people who really cannot drive, and yet they think they're driving safely. They just haven't gotten a crash yet.

I'd rather see mandatory rear running lights. The amount of people who can't be arsed to turn on their lights in bad visibility conditions is too damn high.

[–] acosmichippo@lemmy.world 28 points 2 days ago* (last edited 2 days ago) (1 children)

and on the opposite side don’t turn on your emergency lights while driving in bad weather. you’re only causing confusion by making it seem like you have turn signals on if i can’t see both blinkers.

I still think rear signaling could be improved dramatically by using a wide third-brake light to show the intensity of braking.

For example -- I have seen some aftermarket turn signals which are bars the width of the vehicle, and show a "moving" signal starting in the center and then progressing towards the outer edge of the vehicle.

So now take that idea for brake. When you barely have your foot on the brake pedal, it would light a couple lights in the center of your brake signal. Press a little harder and now it's lighting up 1/4 of the lights from the center towards the outside edge of the vehicle. And when you're pressing the brake pedal to the floor, all of the lights are lit up from the center to the outside edges of the vehicle. The harder you press on the pedal, the more lights are illuminated.

Now you have an immediate indication of just how hard the person in front of you is braking. With the normal on/off brake signals, you don't know what's happening until moments later as you determine how fast you are approaching that car. They could be casually slowing, or they could be locking up their wheels for an accident in front of them.

[–] turtlesareneat@discuss.online 32 points 2 days ago (8 children)

Japan introduced brake lights that increase intensity based on how hard the driver was braking. 20+ years ago. They tested it in the US and drivers found it to be “confusing.”

[–] Celestus@lemm.ee 12 points 2 days ago (4 children)

BMW has implemented this in the US market for the past 20 years or so at least. Under heavy braking, additional brake lights turn on. I believe they call that Brake Force Display. I’m sure they’re not the only manufacturer to do this, too

I think that's a neat idea, but we could instead, collectively, just do better at following other cars at a safe distance. I know it's impractical to expect all drivers on the road everywhere to change their behavior, but it's also persistently frustrating as someone who has for years frequently been stuck in traffic to see 95% of drivers insist on following less than a car-length behind. Following too closely to enable decision-making or accommodate other drivers is the cause of like 98% of both traffic accidents and congestion, according to my completely anecdotal and made up research.

How about reducing the brightness of headlights so I don't feel like the sun is driving at me at night?

Also, if the car is in drive the headlights should go into auto mode. Always see people driving with just parking lights on at sundown.

[–] bridgeenjoyer@sh.itjust.works 10 points 23 hours ago (3 children)

Yes.. WHY DO CARS STILL HAVE 2 SETTINGS LIKE ITS 1935. it would take basically zero effort to have low, high, stun for headlights so the rest of us who drive normal appropriate cars don't have to be blinded by selfish assholes driving a massive truck alone by themselves that they never used for work once in their lives. Yes, im a car person and despise truck posers.

First of all, this would be illegal in many countries.

Second of all: we can differentiate cars by: has red lights, back.

If we lose this option we can no longer differentiate easily if there is a car coming towards us or driving away from us.

[–] CosmicGiraffe@lemmy.world 29 points 2 days ago (2 children)

They tested using a green light for the front brake light, not a red one

Reminded me of this Technology Connections video, in which the dude explained (among other brake-light related things) how some law allows electric vehicles to get away with not using their brake lights: https://www.youtube.com/watch?v=U0YW7x9U5TQ

[–] Obi@sopuli.xyz 12 points 1 day ago (3 children)

Yeah my electric 208 is kinda like that (if I remember the video well, watched it a while ago) but since it's Europe there actually is a regulation about how much a car can decelerate before break lights come on, so instead of making the system turn the lights on they throttle how much it can decelerate for recharge and still makes you use the break to use full regen (and eventually the actual brakes, of course). So it's not a real "one pedal driving".

I’m kind of surprised he made absolutely no mention of manual gearbox vehicles. Some of the problems he’s describing predate EVs and adaptive cruise. I have a manual car and motorcycle. I pretty regularly apply just enough to the brakes to turn the light on without engaging them during engine braking. Engine braking depending on gear choice can be pretty strong. Likely not as aggressive as a regenerative braking system but more than enough to cause issues. I’m certain I’d have been rear ended if I didn’t make the lights turn on while just slowing down, not coming to a full stop.

Wouldn’t better driving education and testing work just as well, if not better?

[–] Almacca@aussie.zone 13 points 1 day ago (10 children)

100% agree, but it's amazing how quickly some people forget their education once they get out on the road, especially after a few years accumulating bad habits. How about less reliance on cars in the first place?

[–] MangoCats@feddit.it 12 points 1 day ago (4 children)

I was having a very hard time seeing any possible benefit of a front brake light, since nobody accident prone ever looks in their mirrors.

I suppose in today's world of automatic transmissions that move the car forward whenever the brakes are released, they might serve some purpose at a four-way stop adding information about immediate intent of the other parties, but even there... that's more of a Darwinian situation where people who get into crashes at four way stops are sorting themselves out from the rest of reasonably competent drivers. If they're going fast enough for injuries at a four way stop, they deserve what they get. If they get a minor fender bender - that's a lesson to read the other traffic better next time.

[–] brygphilomena@lemmy.dbzer0.com 11 points 1 day ago* (last edited 22 hours ago) (8 children)

Id love then to know when someone is slowing down to turn when I'm trying to pull out. So few use turn signals, and even those I don't really trust until the car is noticably getting slower.

Can I have indicators that are in the same place on all cars and not buried in the headlight? That'd be cool.
